The worker installs a hanger to fix the cable to install or check the communication cable by hanging it on the hanging cable hanging on the line, and then inserts the cable to be installed inside the hanger and fastens it to the line. You will be working.

At this time, there was a big problem that the accident that the worker falls in the working state is frequent due to a problem such that the worker suspension cable is broken because it cannot support the weight of the worker. Of course, although the workers rely on simple protective supports such as sitting plates, most of them work only on unstable tension of the ship while working in the air. There is also a problem that the problem is urgently solved because the problem is very low.

In addition, if the pole installed itself is not aged due to aging or impact, the weight is charged when the operator adds a new track or goes up for repair, which causes the pole to collapse.

1 to 4, the automatic installation device 200 of the cable hanger 112 according to an embodiment of the present invention is the main body 210, the guide roller 220, the barbed support shaft 230 and the entrance 240.

The main body 210 forms an outer shape of the automatic installation apparatus 200, and supports the guide roller 220, the barbed support shaft 230, and the access unit 240.

Guide roller 220 is provided with a plurality of rotatably provided in the inner center. Thus, the guide roller 220 is placed on the concave wire 22 for supporting the wire 10. At this time, when the guide roller 220 is forcibly rotated, the main body 210 is moved along the line 22.

Here, the guide roller 220 has a drive motor 212 for transmitting a rotational force to the guide roller 220, so that all or part of the guide roller 220 can be forcibly rotated. The drive motor 212 may be driven by an external power source, but since the automatic installation device 200 is placed on the barbed wire 22 in which the auto installation device 200 is installed high, it is preferable that the driving motor 212 is supplied with power by the battery 214. The structure in which the driving force of the driving motor 212 transmits the rotational force to the guide roller 220 is a general thing. Thus, the power transmission structure of the drive motor 212 and the guide roller 220 is not shown. In addition, the battery 214 is preferably detachably fixed to the main body 210 in various ways. The connection of the driving motor 212 and the battery 214 can be applied in various ways and is not shown.

Although the automatic installation device 200 needs to be made light and low in volume due to the convenience of handling, when light and made less, the friction force between the guide roller 220 and the jaw wire 22 is reduced, and the guide roller 220 is As a slip occurs with respect to the jaw line 22, the main body 210 can not stably move along the jaw line 22.

Thus, the jaw bearing shaft 230 is provided.

The barbed support shaft 230 is rotatably provided in the main body 210 and is in contact with the lower side of the barbed wire 22 on which the guide roller 220 is placed. In particular, the barbed support shaft 230 is preferably disposed between the adjacent guide rollers 220 to support the lower side of the barbed wire 22 corresponding to the pair of adjacent guide rollers 220. This is to prevent the slip line 22 of the guide roller 220 from being rotated and the slip line 22 of the guide roller 220 to be rotated due to the barbed support shaft 230. As the guide roller 220 is prevented from slipping with respect to the barbed wire 22, the main body 210 can be stably moved along the barbed wire 22 even if it is relatively light in weight. Of course, the barbed support shaft 230 may be provided with a separate roller.

Particularly, in a state where the guide roller 220 and the barbed support shaft 230 are installed in the main body 210, the barbed wire 22 is in contact with the lower side of the guide roller 220 and in contact with the top of the barbed support shaft 230, The main body 210 is hard to be installed above the barbed wire 22. Thus, in order for the guide roller 220 to be mounted on the conical line 22, first, the conical line supporting shaft 230 should be disposed to be displaced with respect to the vertical direction with the guide roller 220.

That is, the access portion 240 is provided with the access line support shaft 230 to be accessible in a direction perpendicular to the moving direction of the main body 210 to allow the access line 22 to contact the guide roller 220. .

The access unit 240 includes a holder 242, a positioning hole 244, and a release preventing pin 246.

The holder 242 is provided inside the main body 210, and is formed in a pipe shape so as to insert the barbed support shaft 230 inserted from the outside of the main body 210. The holder 242 is fixedly installed inside the main body 210 by various methods. In addition, the holder 242 and the main body 210 allow the access of the barbed support shaft 230 by passing through holes corresponding to each other. In particular, the holder 242 may be integrally manufactured with the main body 210 or may be detachably fixed to the main body 210.

In addition, the holder 242 passes through one communication hole 243 on the circumferential surface. Of course, the holder 242 is applicable to a variety of shapes and materials.

And, the positioning hole 244 is rectangular through the axial direction of the barbed support shaft 230. That is, the positioning hole part 244 is formed in a slot hole shape along the axial direction on the circumferential surface of the barbed support shaft 230. In this case, the positioning hole part 244 may have a hole shape or a groove shape.

In addition, the release preventing pin 246 is fitted into the communication hole 243 and the positioning hole 244 to maintain the connection bar support shaft 230 with respect to the holder 242. Accordingly, the barbed support shaft 230 is movable along the axial direction of the holder 242 by the length of the positioning hole 244.

That is, when the barbed support shaft is inserted into the holder 242 so that a part of the edge of the barbed support shaft 230 overlaps the guide roller 220 in the vertical direction, the release preventing pin 246 is positioned with the communication hole 243. It is inserted into the setting hole 244.

Thus, the concave line 22 is in contact with the guide roller 220 and the concave line support shaft 230.

In particular, the operator pulls the barbed wire support shaft 230 until the release preventing pin 246 is in contact with either of the inside of the positioning hole 244, and then makes the barbed wire 22 in contact with the guide roller 220. Afterwards, the worker pushes the barley support shaft 230 until the release preventing pin 246 is in contact with the other side of the positioning hole 244. As a result, the barbed support shaft 230 is in contact with the lower side of the barbed wire (22). Of course, since the barley support shaft 230 is applying tension to the barley wire 22, the barbed support shaft 230 is not drawn out from the holder 242 arbitrarily.

The jaw bearing shaft 230 can be modified into various shapes.

Accordingly, the electric wire 10 is connected to the neighboring first pole 2 and the second pole 4 spaced apart by the set distance, and the cable hanger 112 is adjacent to the adjacent first pole 2 and the second pole ( 4) is connected.

Then, the cable hanger 112 is connected to the upper fixing wire 212 and the lower fixing wire 222 to maintain the arrangement state at equal intervals.

In more detail, the electric wire 10 is supported by the clamp 8 to the spaced first pole 2 and the second pole 4. Of course, the wire 10 may be connected to the first pole 2 and the second pole 4 by various methods. In addition, the clam wire 22 is disposed on the upper side of the electric wire 10 and fixedly connected to the first pole 2 and the second pole 4 corresponding to both sides. At this time, both ends of the jaw wire 22 is connected and fixed to the first pole 2 and the second pole 4 by various methods.

In addition, the upper fixing wire 212 is continuously inserted above the plurality of cable hangers 112, the lower fixing wire 222 is continuously inserted below the cable hanger 112, the upper fixing wire 212 is inserted. . At this time, the upper fixing wire 212 and the lower fixing wire 222 arranges the cable hangers 112 at equal intervals, and restrains each of the cable hangers 112 to maintain the equally spaced arrangement of the cable hangers 112.

For example, the upper fixing wires 212 and the lower fixing wires 222 fix each of the cable hangers 112 by various methods such as clips.

In particular, as in FIGS. 5 to 7, the cable hanger 112 includes a ring body 130, an upper connector 140, and a lower connector 150.

The ring body 130 forms an outer shape of the cable hanger 112 and is formed in a substantially ring shape, and inserts an electric wire 10 such as an optical cable connecting base stations or power lines for transmitting power of a power plant to the inside. In order to form the receiving portion 136, a part of the circumferential surface is opened. That is, the ring body 130 is formed discontinuously along the closed curve trajectory by the receiving portion 136.

In addition, the ring body 130 may be formed in a circular shape, it is preferably formed in a non-linear. Nonlinear refers to things that are not straight.

Then, the ring body 130 inserts the barbed wire 22 into the upper upper side. At this time, both ends of the clam wire 22 and the wire 10 are connected to a pole and the like. Thus, the strand 22 and the wire 10 are arranged side by side with each other. The wire 10 is made of a relatively thick or bundle and bent downward. Therefore, the cable hanger 112 is supported by a relatively strong tension line 22 to support the wire 10 with a relatively low tension serves to prevent sagging and damage of the wire (10).

That is, the concave wire 22 is inserted in the upper side of the ring body 130 of the cable hanger 112, the electric wire 10 is inserted in the inner lower side of the ring body 130. Here, when the ring body 130 is inserted into the concave wire 22 inside the non-linear shape, the concave line 22 is moved along the circumferential direction of the ring body 130, the ring body 130 is unstable wire ( 10) will be mounted. Thus, the ring body 130 preferably forms a support part 132 by protruding the upper inside upward to accommodate the concave wires 22.

The support part 132 protrudes upward from the nonlinear trajectory of the ring body 130 and is formed to accommodate the concave wire 22 therein. Of course, the support 132 may be modified in various shapes. In addition, the support 132 may be separately formed in the ring body 130, but is preferably formed in the ring body 130 itself. The inner side of the support portion 132 is formed larger than the thickness of the concave wire 22 so that it can be easily passed when there is a resistor (such as a strap for binding) on the concave wire 22 during the transport installation of the cable hanger 112.

As a result, the concave wire 22 is inserted inside the support 132 of the ring body 130, so that the concave wire 22 cannot move along the circumferential direction of the ring body 130, and thus, the electric wire 10 Is stably mounted inside the ring body 130.

In particular, the cable hanger 112 may be made of a variety of materials, it may be made of a steel material with a large internal stress so that the mounting of the wire 10 with respect to the clam wire 22 can be stably.

At this time, the ring body 130 is preferably to reduce the friction of the wire 10, to form an insulating coating member 134 on the circumferential surface for insulation. The insulating coating member 134 is made of an insulating material, and may be formed by double injection or separately provided in the ring body 130 to cover the ring body 130. In particular, the insulating coating member 134 is preferably to stably mount the wire 10 by increasing the surface area of the inner side to increase the contact area with the wire 10. For convenience, the insulating coating member 134 is shown to be able to insert the ring body 130 in the open state to cut open. Of course, the insulating coating member 134 is returned to the initial state when the external force to be removed and completely surrounds the ring body 130 along the circumferential direction. In addition, the insulating coating member 134 is provided in the ring body 130 to surround the ring body 130 that can be in contact with the wire 10 as a whole, of the ring body 130 is cut by the receiving portion 136 It is formed to extend from the end adjacent to the wire 10 inserted into the cable hanger 112 of the both ends to allow the predetermined wheel to elastically protect the sheath of the wire 10 inserted into the ring body 130 and the wire It is preferable to prevent the random departure of (10).

 On the other hand, the upper connecting portion 140 is formed on the upper side of the ring body 130 so that both sides are formed to insert the upper fixing wire 212 connected to the corresponding pole, the lower connecting portion 150 is the ring body 130 Is formed on the lower side of both sides is formed to be inserted into the lower fixing wire 222 connected to the corresponding pole.

At this time, the upper connecting portion 140 and the lower connecting portion 150, like the support portion 132, may be integrally formed on the ring body 130, may be formed detachably to the ring body 130.

In particular, the upper connecting portion 140 is preferably formed on the circumferential surface of the support 132, the lower connecting portion 150 is preferably formed in the lower central portion of the ring body 130.

The upper fixing wires 212 and the lower fixing wires 222 arrange and fix the plurality of cable hangers 112 to be spaced at a predetermined interval (equal interval). When the upper fixing wire 212 and the lower fixing wire 222 deploys the plurality of cable hangers 112 at equal intervals, the cable hangers 112 are kept vertical or approximately vertical.

Here, the reason why the ring body 130 is inserted into the upper fixing wire 212 and the lower fixing wire 222, when only the upper fixing wire 212 is connected to the ring body 130, the wire 10 and the cable hanger ( This is because the lower side of the cable hanger 112 does not follow when the upper fixing wire 212 is pulled for installation due to the frictional resistance of 112.

In addition, the upper fixing wire 212 is located at the same height as the line 22, or the side of the side line 22, the upper connecting portion 140 is provided on the support 132. This is to prevent the upper connecting portion 140 from being damaged due to the friction of the bare wires 22 when the upper fixing wire 212 is connected to the upper side of the cable hanger 112.

In particular, as the lower connecting portion 150 is formed convexly to the lower side of the ring body 130, the insulating coating member 134 is formed below the ring body 130 except for the lower connecting portion 150. Thus, the insulating coating member 134 blocks the passage connecting the inside of the lower connecting portion 150 and the inside of the ring body 130. This is to prevent the lower fixing wire 222 from leaving the lower connector 150. In addition, the lower connection portion 150 is formed by passing through the lower side of the ring body 130, or cut the lower portion of the insulating coating member 134 to connect the lower fixing wire 222, such as the lower side of the cable hanger 112 In various ways.

As a result, the ring body 130 of the cable hanger 112 inserts the bare wires 22 into the upper side and the wire 10 into the lower side of the inner side, and the upper fixing wires 212 and the lower fixing wires 222. By inserting the corresponding upper connecting portion 140 and the lower connecting portion 150, respectively, the ring body 130 is supported by the barbed wire 22 while receiving the wire 10 to prevent sagging of the wire 10. Then, the ring body 130 is moved along the line 22 by the movement of the main body 210 of the upper fixing wire 212 and the lower fixing wire 222.

On the other hand, the cable hanger 112 is provided with an automatic installation device 200 that is placed on the moving line 22 to be automatically arranged at equal intervals along the line 22.

The main body 210 of the automatic installation apparatus 200 is positioned between an adjacent pair of cable hangers 112 among a plurality of cable hangers 112 connected to the upper fixing wires 212 and the lower fixing wires 222. 22).

Subsequently, as the guide roller 220 of the main body 210 and the barbed support shaft 230 are rotated while applying sufficient friction to the barbed wire 22, the main body 210 moves along the barbed wire 22 to move forward. The outermost cable hanger 112 is pushed against. Then, while the outermost cable hangers 112 of the plurality of cable hangers 112 are moved by the main body 210, the plurality of cable hangers 112 are gradually disposed along the line 22 at equal intervals. .

At this time, the upper fixing wire 212 and the lower fixing wire 222 is fixed to each cable hanger 112 to position the plurality of cable hangers 112 at equal intervals. Particularly, the upper fixing wire 212 and the lower fixing wire 222 are fixedly connected to the first pole 2 or the second pole 6 to which one side corresponds, or fixedly connected to the same position of the barbed wire 22. Once fully pulled, each cable hanger 112 is preferably kept upright.

On the other hand, the main body 210 can directly push the cable hanger 112, but the main body 210 as the advance to the inner wire 22, the wire 10, the upper fixed wire 212 and the lower fixed wire ( 222) must be transported to ensure space. As a result, the main body 210 cannot directly push the cable hanger 112.

Accordingly, the main body 210 includes a lever 252 on the front side. The lever 252 allows the feed of the barbed wire 22, the electric wire 10, the upper fixing wire 212 and the lower fixing wire 222, and serves to push the cable hanger 112.

At this time, the lever 252 is installed so as not to interfere with the coarse wire 22, the wire 10, the upper fixing wire 212 and the lower fixing wire 222 when the main body 210 is installed on the concave wire 22. desirable. Therefore, the lever 252 is provided in the front side of the main body 210 so that rotation is possible.

In particular, the lever 252 is in a folded state so as not to interfere with the coarse wire 22, the electric wire 10, the upper fixing wire 212 and the lower fixing wire 222, and a state in which it is erected to push the cable hanger 112. To hold, the body 210 has a stopper 254.

Thus, the lever 252 is kept in contact with one side of the stopper 254 in a folded state, and maintains a state in which the lever 252 is in contact with the other side of the stopper 254. Of course, the stopper 254 may be detachably provided at the main body 210 or may be integrally formed at the main body 210.

The lever 252 may interfere with the stopper 254 when rotated. Therefore, the lever 252 is preferably rotated in a state of being pulled to the front side of the main body 210 before the rotation, and is repositioned so as to be caught by the stopper 254 after the rotation.

For example, a flange 258 is formed at an end of the lever 252 inserted into the main body 210, and the lever 252 axially inserts the elastic member 256. At this time, one side of the elastic member 256 is in contact with the flange 258, the other side of the elastic member 256 is in contact with the inside of the main body 210. Accordingly, when the lever 252 is pulled to the front side of the main body 210, the lever 252 is pulled out of the main body 210, the elastic member 256 is compressed. Thereafter, the lever 252 is returned to the initial state by the elastic restoring force of the elastic member 256 when removing the external force pulled after the rotation. At this time, the 'initial state' refers to the degree to which the lever 252 is inserted into the main body 210 by the length or thickness of the elastic member 256 in the external force removed state.

For convenience, the elastic member 256 is shown as a coil spring.

In particular, the main body 210 may be provided with a weight on the opposite side when the body 210 is inclined toward either side.
